Based on the Broadway musical, Into the Woods follows the classic tales of Cinderella, Little Red Riding Hood, Jack and the Beanstalk and Rapunzel, when a baker (James Corden) and his wife (Blunt) want to begin a family despite their interaction with a witch (Streep), who put a curse on them.
Johnny Depp, who plays The Wolf, had nothing but good things to say about director Rob Marshall (Chicago).
"His approach is very pure and he's out there to make something beautiful," said Depp. "He's the real thing."
Anna Kendrick, who plays Cinderella, has big plans for the film's Christmas Day premiere.
"I'm going to be home for Christmas this year, so I'm going to see it in the theatres with my parents," said Kendrick. "I feel I have very warm, fuzzy feelings about the prospect of seeing this movie with my family."
